What are enum Flags in TypeScript?

Question

I\'m learning TypeScript using this ebook as a reference. I\'ve checked the TypeScript Official Documentation but I don\'t find information about enum flags.

Answer 1

enum Info{
    None = 0,
    glass= 1 << 0, // 0001 -- the bitshift is unnecessary, but done for consistency
    plastic= 1 << 1,     // 0010

}
